I think the problem is that when we call explain_invalid_constexpr_fn, we don't
have current_class_ptr/_ref available, so then build_data_member_initialization
doesn't go here:

      else if (op == current_class_ptr
               && (same_type_ignoring_top_level_qualifiers_p
                   (TREE_TYPE (TREE_TYPE (member)),
                    current_class_type)))
        /* Delegating constructor.  */
        member = op;
